SP47 Presents a collection of 17 papers on freeze-thaw problems, performance of concrete in seawater, and sulfate attack, to help advance understanding of the response of concrete to attack by aggressive elements. Knowledge of the mechanism, the development of a course of action, and a report of the field experience are all necessary contributions to improving our knowledge of concrete durability. SuccessfuI performance of concrete is dependent to a greater extent on its durability against the environment than on strength properties.
